Quick Start
Check Format
hytale_get_format_info
# Returns: formatType, blockSize, nodeCount, features
Validate Model
hytale_validate_model
# Returns: valid, nodeCount, issues
Cube Properties
Set Shading Mode
hytale_set_cube_properties: cube_id="crystal", shading_mode="fullbright"
Enable Double-Sided
hytale_set_cube_properties: cube_id="cloth", double_sided=true
Set Stretch
hytale_set_cube_stretch: cube_id="arm", stretch=[1.2, 1.0, 1.0]
Quads (2D Planes)
Create single-face planes:
hytale_create_quad: name="leaf",
position=[0, 16, 0],
normal="+Y", # +X, -X, +Y, -Y, +Z, -Z
size=[8, 8],
double_sided=true
Attachments
List Attachments
hytale_list_attachments
Mark as Attachment Piece
hytale_set_attachment_piece: group_name="hand_right", is_piece=true
This bone will attach to hand_right on the base model.
List Attachment Pieces
hytale_list_attachment_pieces
Animation
Visibility Keyframe
Toggle bone visibility during animation:
hytale_create_visibility_keyframe:
bone_name="weapon_sheathed",
time=0.5,
visible=false
hytale_create_visibility_keyframe:
bone_name="weapon_drawn",
time=0.5,
visible=true
Set Loop Mode
hytale_set_animation_loop: animation_id="walk", loop_mode="loop"
hytale_set_animation_loop: animation_id="attack", loop_mode="once"
hytale_set_animation_loop: animation_id="death", loop_mode="hold"
Common Workflows
Create Character Model
# 1. Create project (use bedrock format, Hytale format activates automatically)
create_project: name="goblin", format="bedrock"
# 2. Build bone hierarchy
add_group: name="root", origin=[0, 0, 0]
add_group: name="body", parent="root", origin=[0, 12, 0]
add_group: name="head", parent="body", origin=[0, 24, 0]
add_group: name="arm_left", parent="body", origin=[6, 22, 0]
add_group: name="arm_right", parent="body", origin=[-6, 22, 0]
add_group: name="hand_right", parent="arm_right", origin=[-8, 16, 0]
# 3. Add geometry
place_cube: elements=[{name: "torso", from: [-4, 12, -2], to: [4, 24, 2]}], group="body"
# 4. Set Hytale properties
hytale_set_cube_properties: cube_id="eyes", shading_mode="fullbright"
# 5. Validate
hytale_validate_model
Create Weapon Attachment
# 1. Create attachment structure
add_group: name="hand_right", origin=[0, 0, 0]
# 2. Add weapon geometry
place_cube: elements=[{name: "blade", from: [-0.5, 0, -0.5], to: [0.5, 24, 0.5]}], group="hand_right"
# 3. Mark as attachment piece
hytale_set_attachment_piece: group_name="hand_right", is_piece=true
# 4. Add glowing effect
hytale_set_cube_properties: cube_id="rune", shading_mode="fullbright"
Animate Weapon Draw
# Start with sheathed weapon visible
hytale_create_visibility_keyframe: bone_name="sword_sheathed", time=0, visible=true
hytale_create_visibility_keyframe: bone_name="sword_drawn", time=0, visible=false
# At draw point, swap
hytale_create_visibility_keyframe: bone_name="sword_sheathed", time=0.3, visible=false
hytale_create_visibility_keyframe: bone_name="sword_drawn", time=0.3, visible=true
Tips
- Always run
hytale_validate_model before export - Keep node count under 255
- Use stretch instead of fractional cube sizes
- Set group origins at joint/pivot points
- Use
fullbright shading for glowing elements - Mark equipment bones as
is_piece=true for attachments - Use visibility keyframes for state changes (weapons, damage)
- Animation runs at 60 FPS (time 1.0 = 60 frames)
